05-06 rsx solution Question

tmartin · Post by **tmartin** » Tue Feb 10, 2009 3:20 pm

If we used the below item to convert the signal before hitting the ECU from the 05-06 rsx transmission to be the same as the 02-04 rsx transmission wouldnt the cruise control issue be resolved? In KPro we would then need to deselect the 05-06 conversion option but outside of this we would regain control of our cruise control. True? I ask this because we also have the same issue if we want to do the EPS swap into the 05-06 as well and we are hoping this devise will resolve this as well. I am under the assumption that the gauge cluster for the 05-06 is the same frequency as used in the 02-04 as well.

Thank you

The VSS runs on 5 volts, not 12, so this thing will put 12 volts into a 5 volt signal and will damage the ecu and possibly the K-Pro as well. I highly advise against using this as it will probably cause more problems than what you are trying to fix.

It would not be a 12 volt into a 5 volt.

12volt power wire for the device
ground wire and then
signal in and out wire which is designed to convert the 05-06 vss to 02-04 frequency

Since this is a Hybrid Racing Product, you may want to contact them about this.

I understand your response so lets take them out of the equation.

Question:

If you can change the 05-06rsx vss frequency to match the 02-04 before hitting the KPro ECU then in theory deselecting the 05-06 speedo conversion option within KManager would be the only thing you would need to do. With this said the cruise control option for 05-06 rsx users would then be corrected and cruise control would be restored. True?

Thank you

No, only the ecu will receive the signal, but the guage cluster will not.

Why would the guage cluster not receive the signal? From my understanding the guage cluster on the 05-06 is the same frequency as the 02-04 rsx.

Can you tell me what kind of signal goes to the speedo if the countershaft option in KManager is selected and when it is not selected?

Thanks again

This is something which you would have to try to determine if it will work - we can't support modified chassis harnesses and 3rd party products. You would have to re-wire the chassis harness to take control of the signal from the ECU to dash. The 05-06 signal from the ECU to dash is similar to the 02-04, but may not be exactly the same. If the 02-04 and 05-06 clusters are interchangable and show the same speed when switched between the same vehicle then that will tell you the if they are the same. It may or may not help the cruise control stability - again, testing this would be the only way to find out.

Thank you for the response and I do understand your position and appreciate the response on this. I will give an update at the end of the month as we will be doing this for an EPS swap then.

Well this past weekend we tackled the electronic power steering project on my 06 RSX Type-S and had great success.

Other RSX owners have been unsuccessful in getting the eps rack to work on the 05-06 rsx because these rsxs use a high frequency vss signal. Hybrid racing came out with a converter to change that high frequency signal to a low frequency signal which it does well. So once it is wired in we were able to uncheck the countershaft driven speedsensor option in kmanager and the guage cluster and rack worked.

When we first started this on Sat our goal was to determine whether or not the 06 guage cluster ran off a low or high frequency signal and it was found that it runs off a low frequency signal. I was shocked that you (hondata) did not know this or just chose to not disclose this information for whatever reason which is perfectly fine. Either way a few tests and we had the frequency identified. Once we had the speedo in the dash working correctly we knew the rack would work as well which was the case.

There are few side affects of this install which a couple are good and one is not so good. The good news is that cruise control now works for me which it never had before for any length of time and also the speedo does not periodically drop off anymore which is why cruise would kick off on us. The not so good news is that the hybrid device is calibrated for 15" wheels and not 17" wheels so the speedo is off. We are currently looking into a few options for this as well.

While putting in an EPS rack is not for everyone it was a great mod for me since we are working on putting a Lysholm Twinscrew blower in the car. With that said this speed converter seems like it would be a good item for those of you who like your cruise control. Once we have the calibration of the speed issue resolved I will post up.

Thank you

I wanted to update the thread and let everyone know I was able to not only get my EPS rack working but also calibrate for wheel size using the Dakota Digital device.

The Dakota Digital unit works WONDERFUL. I was able to easily calibrate for my wheel size and the best part it is only 79.95 bucks and some shipping compared to $200 for the Hybrid. It wires in the same as the Hybrid with one additional ground for the unit itself which I grounded on the frame.

12 volt - same as Hybrid
ground - same as Hybrid
Sensor Ground - Ground on the frame somewhere
Speed input signal - same as Hybrid
Calibrated AC output signal - same as Hybrid

Switch settings are as follows:

#1 - on
#2 - on
#3 - on
#4 - off

Here is a link to my site with the whole install and more.
